FLUX 3 AI Video Generator (flux3app.com)

FLUX 3 AI Video Generator is a web workspace for creating AI video from text prompts, a single image, first and last frames, or up to 10 keyframes using the FLUX 3 model. It is built for individual creators, brand and design teams, and others producing short video content for advertising, social media, or storytelling.

Users describe the desired scene, upload supported image references such as a starting image or keyframes, choose the duration, aspect ratio, resolution, and audio setting, then submit the request and track its progress in a creation history until the finished video can be previewed and downloaded.

FLUX 3 generates coherent motion between visual anchors, produces optional synchronized audio including dialogue and sound effects, and supports text-to-video, image-to-video, and keyframe-guided generation with defined start and end frames. Output controls let users set duration, aspect ratio, and resolution before generating.

Credits are calculated by output duration and resolution: 720p uses 10 credits per second and 1080p uses 18 credits per second, the same rate across all input modes. Monthly plans range from a Creator tier at $29/month with 580 credits to a Studio tier at $199/month with 9,950 credits, billed monthly or yearly.
